Installation and commissioning are not the same thing. This distinction matters enormously, and most clients don’t know it exists until something goes wrong six weeks after the crew packs up and leaves.
Installation is putting hardware in place. Mounting the displays, running the cables, racking the equipment, connecting the devices. It’s the physical work. Commissioning is verifying that everything installed actually works the way it’s supposed to, tuning the system to the specific room and use case, and documenting what was done so the system can be maintained and supported over its operational life.
A system that’s installed but not commissioned is a system that was put in a room and turned on. Whether it performs correctly is basically unknown. Whether the audio levels are right, whether the camera covers every seat, whether the control system fires every macro correctly, whether the network handles the traffic load reliably, whether the lighting settings are calibrated to the room’s actual conditions. All of that is unknown until it’s tested and verified.
This article covers what commissioning actually involves, why it matters, what good commissioning looks like for each component of a commercial AV system, and how to know whether a system has been properly commissioned or just installed.
Why Commissioning Gets Skipped
Commissioning is sometimes treated as optional or as something that happens naturally during installation. Neither is true.
The pressure on installation timelines in commercial projects is significant. Space is under construction until the last possible moment. The AV installation gets compressed into whatever time is left before occupancy. The crew installs, connects, and power-cycles everything, confirms that the screens turn on and the speakers make sound, and hands over the room.
That’s not commissioning. That’s a power-on test. The difference is everything that happens between “this device powers on” and “this system performs correctly for its intended use case in this specific room.”
Proper commissioning takes time that compressed timelines often don’t have. It requires measurement equipment. It requires the room to be in its finished state, with furniture, flooring, and finished surfaces in place, because those elements affect audio performance significantly. It requires test content and test calls, not just a power-on verification.
The result of skipping commissioning shows up in the first few months of operation. Audio levels that aren’t right for the room. Camera framing that cuts off half the table. Macros that almost work but fail intermittently. Control system touchpanels that behave differently in different rooms. Network bandwidth that holds up fine with two users and falls apart with eight simultaneous video calls.
Each of these problems generates a service call. Each service call costs money and creates friction. A properly commissioned system generates far fewer service calls because the problems were found and fixed before the room went live.
What Commissioning Covers Component by Component
Commercial AV systems have multiple subsystems, and each requires its own commissioning process. A complete commissioning covers all of them, not just the most visible components.
Display and Video Signal Path
Every display in the system needs to be verified for correct image output, proper input switching, color calibration, and mounting security.
Power on the display and confirm it reaches operating temperature without issues. Cycle through every input and verify that the correct source appears on the correct display. Verify that input switching from the control system works correctly on every command.
Check the display’s color settings. Factory defaults are often set to a punchy, saturated consumer mode that looks impressive in a showroom and looks wrong in a professional environment. Professional settings, often labeled “ISF,” “Custom,” or “Calm” depending on the manufacturer, produce a more accurate, professional image appropriate for a conference room or presentation space.
Verify mounting security. Tilting, articulating, and ceiling-mounted displays need to be checked under load conditions. A display that seems secure when first mounted can develop movement over time if the fasteners weren’t torqued correctly or the wall surface wasn’t properly reinforced. Commercial display installation on commercial-grade mounts rated for the display weight is the baseline requirement. Commissioning includes confirming that every mounting point is correctly rated and secured.
For digital signage deployments, the commissioning step adds verification that the media player is receiving content from the CMS, that scheduled content switches correctly at the programmed times, and that the display enters standby and wakes correctly on schedule.
Audio System
Audio commissioning is the most technically involved part of the process and the one most frequently shortchanged. It requires measurement equipment and a methodical approach through the entire signal chain.
Start at the microphone and work forward. Place a calibrated measurement microphone at each seat position at the table and measure the capture level from each position. This tells you whether the microphone coverage is adequate across the full seating area. Any seat where the captured level is significantly below the target reveals a coverage gap that needs to be addressed before the room goes live.
Verify the signal path from microphone to codec to speakers. Check that echo cancellation is active and configured correctly for the room. Run a test call and listen to the audio from the remote end, which is what matters for a conferencing room. Have someone speak from every seat and verify that remote participants can hear clearly from all positions.
Measure and set speaker output levels. The target is a natural, conversational volume level that’s clearly audible without being uncomfortably loud. In rooms where volume levels were set by ear during installation rather than measured, they’re often wrong by 6 to 10 dB in one direction or the other. Too loud and the room creates feedback risk and fatigues participants. Too quiet and remote participants have to strain to hear.
Professional audio installation for commercial spaces includes DSP programming that’s specific to the room dimensions and acoustic characteristics. Commissioning includes verifying that the DSP parameters are correctly set, not just that the DSP is present in the rack.
For rooms with dedicated amplification, verify that all amplifier channels are properly assigned to the correct speaker zones, that gains are matched across zones, and that the system handles simultaneous playback in multiple zones correctly.
Video Conferencing System
The video conferencing system commissioning is really a test of the entire room’s AV performance as experienced by remote participants, not just individual component verification.
Run a test call with a remote participant who can give you honest feedback on audio and video quality. Have someone sit in every seat in the room during the test and speak normally. Remote participants need to confirm that every seat is audible at consistent volume and that the camera framing includes all participants. Any seat that’s inaudible or out of frame reveals a gap that needs addressing.
Verify camera height and angle. The camera should be at roughly eye level when seated, which for most conference rooms means the center of the display is between 48 and 60 inches from the floor and the camera sits just above the top edge. A camera mounted too high or too low makes participants appear to be looking away from the person they’re talking to, which makes remote engagement harder.
Verify auto-framing behavior if the camera has that feature. Walk through the room, sit in different seats, speak from different positions. The framing should follow participants naturally without excessive jerking or false triggers from background movement. If the auto-framing is triggering incorrectly, it needs to be tuned or disabled before the room goes live.
Video conferencing system installation includes the full setup of camera, microphone, and codec, but commissioning verifies that the combination actually performs for the specific room rather than just functioning in isolation.
Verify platform integration. Join a real meeting on the room’s primary platform, confirm that the calendar integration shows upcoming meetings on the room panel, verify that one-touch join works correctly, and confirm that the display input switches automatically when a call starts.
Network and Connectivity
Network commissioning is where a lot of commercial AV systems have hidden problems that don’t surface until the room is under real load.
Test network connectivity at every device endpoint. Every display, every camera, every codec, every control system processor should be on a wired connection where infrastructure allows. Verify IP addressing, confirm that each device is reachable from the management network, and verify that any network segmentation for AV devices is correctly configured.
Run bandwidth tests at each conferencing endpoint. A room that’s supposed to handle 1080p video conferencing needs to sustain at least 5 Mbps of upload and download without packet loss. Run the test during business hours when the network is under normal load, not at 6 AM on a Sunday when load is minimal.
Verify QoS configuration. Traffic prioritization rules should be in place so that video conferencing traffic gets priority over background data transfers. Check that the rules are actually working by running a video call while simultaneously generating background network load on the same network segment. Call quality should remain stable.
Commercial network infrastructure designed specifically for AV environments includes VLAN segmentation and QoS policies. Commissioning confirms these are correctly implemented, not just that the hardware is installed.
Test Wi-Fi coverage if wireless devices are part of the system. Any device that depends on wireless connectivity needs adequate signal strength at its installation location. A wireless controller or wireless presenter adapter that works perfectly during installation on a quiet day can fail under load during a real meeting if the access point coverage is marginal.
Control System
Control system commissioning is methodical and thorough. Every button on every interface needs to be tested for every function it’s supposed to perform.
Create a test matrix: every control input (touchpanel button, keypad press, scheduled trigger, sensor event) mapped to every expected output (display power, input switch, volume change, lighting scene, shade position, macro execution). Work through the matrix systematically. Any function that doesn’t work as expected gets documented and fixed before sign-off.
Test macros in sequence, not just individually. A macro that powers on the display correctly and a macro that adjusts audio levels correctly may still conflict when run together if the sequencing isn’t right. The “Call Start” macro needs to fire every element in the correct order, with appropriate delays between commands where the hardware needs time to respond.
Test failure recovery. What happens if the room loses power during a meeting and comes back online? Does the system restore to a sensible default state or does it come up in an undefined condition that requires manual intervention? Good control system programming includes power-on defaults that bring the room to a usable state automatically.
Lutron lighting control systems integrated with the main control system need separate commissioning for the lighting scenes themselves, confirming that every scene preset produces the correct output at every fixture, and that the scenes fire correctly when called from the main control interface.
Smart home automation systems at the residential scale go through the same control commissioning process, verifying that every automation trigger produces the expected response across all connected devices.
Lighting
Lighting commissioning for rooms used for video calls involves measurement, not just a visual check.
Measure illuminance at face height at each seat position. The target range for video conferencing environments is 300 to 500 lux at face level. Any seat significantly below this threshold will produce degraded camera quality for the participant in that position.
Verify color temperature consistency across all light sources in the room. Mixed color temperatures produce camera white balance problems that make people look off. All artificial sources in the room should be at a consistent color temperature, ideally in the 3000K to 3500K range.
Verify dimming behavior. Confirm that dimmers produce smooth, linear dimming without flickering at any level, that fixtures come to the same level when recalled from a scene preset, and that the dimmer to LED compatibility is correct for the specific bulb type installed. LED dimmer compatibility problems show up as flickering, popping, or an inability to dim below a certain percentage.
Home theater installation involves the same lighting commissioning for theatrical lighting systems, where scene presets for movie viewing, intermission, and discussion modes need to be verified and tuned for the specific room before the client takes over the space.
Documentation: The Part That Makes the System Maintainable
A commissioned system without documentation is a system that’s one technician turnover away from being unmaintainable. Documentation is half of what commissioning produces.
The commissioning documentation package for a commercial AV system should include:
As-built drawings showing the actual cable routing, device locations, and rack layout as installed (not as designed, which often differs from reality). Every cable labeled in the drawings with the label that’s physically on the cable in the field.
An equipment list with model numbers, serial numbers, firmware versions at commissioning, IP addresses, and locations for every component in the system.
DSP programming documentation showing the signal flow, gain structure, and parameter settings for the audio system. This is what allows a future technician to restore the system to its commissioned state after a firmware update changes a setting or a DSP unit needs to be replaced.
Control system program files and documentation of every function, macro, and interface page in the control system. The compiled program files should be backed up off-site, not just stored on the processor.
Test results showing the measurements taken during commissioning: audio levels at each seat, illuminance measurements, network bandwidth test results, and camera framing verification. This baseline documentation makes future service calls more efficient because the technician knows what “correct” looks like.
User documentation explaining how the system works for the people who’ll be using the room. Not technical documentation. Plain-language instructions for the most common use cases.
Smart home and automation system commissioning produces the same documentation package at the residential scale, which matters just as much when a homeowner wants to add a device years after installation or needs to troubleshoot an automation behavior.
User Training: The Step That Determines Adoption
A system that nobody knows how to use doesn’t get used. Or gets used wrong, which generates service calls that are really training calls.
User training at commissioning should cover the primary use cases for the room, not comprehensive technical training. For a conference room, that means how to start a call, how to adjust volume, how to share content, and how to end a call cleanly. Five minutes with the actual people who’ll use the room, on the actual system, in the actual room.
For rooms with more complex functionality, a quick-reference guide posted in the room or attached to the control panel gives users a reference for less common tasks without requiring them to call support.
The people who need training are often not the people who signed the contract. The executive who approved the project uses the room differently than the administrative assistant who books it and the marketing team who uses it for client presentations. Each user group benefits from a brief walkthrough focused on their specific use patterns.
Commercial AV systems that include training as part of the commissioning process have measurably better adoption rates and generate fewer service calls in the first year of operation than systems delivered with hardware only.
What to Check Before Accepting a Commissioned System
If you’re on the client side of a commercial AV installation and want to verify that commissioning was done properly before signing off, here’s what to check.
Ask for the commissioning documentation. If the integrator can’t provide as-built drawings, equipment serial numbers, DSP settings, and test results, the commissioning wasn’t complete.
Sit in every seat in every conference room and make a test call. Speak from each seat at normal conversational volume. Listen to the recording of the call or get feedback from the remote participant on whether you were clearly audible. This takes thirty minutes and reveals coverage gaps that no amount of documentation review would catch.
Test every button and every macro on the control system. Not a demonstration of the main scenarios. Every button. In a properly commissioned system, everything works. In an installed-but-not-commissioned system, you’ll find things that almost work, or work most of the time, or work individually but not in sequence.
Confirm that firmware is current on every device. A commissioning that left devices on factory firmware from a year ago is a system that has known security vulnerabilities and potential compatibility issues already.
Ask what happens if the internet goes down. Does the room still work for in-person meetings? Does the control system restore correctly after a power outage? A properly commissioned system has answers to these questions because they were tested during commissioning.
Mounting NYC includes commissioning as a defined, documented phase of every commercial installation, not as an optional add-on. The technical documentation, test results, and user training that come with a properly commissioned system are what protect the client’s investment over the system’s operational life, and they’re what allow the system to be maintained and extended without starting from scratch every time something changes.
Commissioning is not the exciting part of an AV project. It doesn’t have the visual appeal of hardware being installed or the before-and-after satisfaction of a room transformation. But it’s the part that determines whether the system performs correctly a year from now, two years from now, when the original installation crew is long gone and someone else needs to understand what was built and how it works.
A system that’s installed is furniture. A system that’s commissioned is infrastructure
